Ace Combat: Infinity’s beta will start next week on December 12 and run through December 18 in Japan. The tester includes online co-op battles, single-player campaign mode, and a tutorial for Test Flight Mode. Aircraft can also be customized and save data will transfer over to the full game when it goes live later this month. A beta video is below. Ace Combat: Infinity is the series’ first foray into free-to-play, and is being published by Namco-Bandai on PlayStation 3 before the end of the year. Thanks, Gematsu.
